Hi Thank you for your comment on my blog. Cycling rocks and is the best exercise out there, in my opinion. I love my bikes - they live indoors. Happily I live right on the edge of Norwich, in Norfolk so I have some great countryside to ride through and nothing too hideous in the way of hills. I have some brilliant headphones too, so I can listen to music. I have Aftershokz bone conduction headphones so I hear through my bones leaving my ears free so I can hear everything going on about me. I can highly recommend them if you like a bit of inspiration going up hills.
